The Grammy-winning entertainer has more than 30 million followers on Twitter and that's where she shared a link this week to a short video showing her doing a striptease and fooling around in a bathtub with two other women.

She told her followers that it's a "surprise for you, almost ready for you to TASTE."

Then, in between concerts in Brazil and Argentina, she posted a picture Thursday on her Twitter page showing her wallowing in her underwear and impossibly high heels on top of the remains of what appears to be a strawberry shortcake.

"The real CAKE isn't HAVING what you want, it's DOING what you want," she tweeted.

Lady Gaga wore decidedly unglamorous baggy jeans and a blouse outside her Buenos Aires hotel Thursday as three burly bodyguards kept her fans at bay. Another pre-concert media event where she was supposed to be given "guest of honor" status by the city government Friday afternoon was cancelled.

After Argentina, she is scheduled to perform in Santiago, Chile; Lima, Peru; and Asuncion, Paraguay, before taking her "Born This Way Ball" tour to Africa, Europe and North America.
